SUPPORTING AND OPERATING CHEMICAL FIRE-EXTINGUISHERS.

SPECIFICATION forming part of Letters Patent No. 297.687, dated April 29, 1884-.

Application filed November 16, 1883.

ful Improvement in Supporting and Operat= ing Chemical Fire-Extinguishers, of which the following is a specificatiom My invention relates to what are commonly known as chemical or bottle-breaking firero extinguishers, in which pressure is generated by the combining of two or more chemicals or substances, one of which is commonly con tained in the extinguisher until the latter is to be used, when the bottle is broken and the I 5 chemical or substance liberated.

The invention is applicable to extinguishers which are too large to be carried on the hack and which remain stationary even when in use, the hose, which is permanently connected with them, being commonly coiled or reeled up near them and extended for use when necessary.

One object of my invention isto enable the extinguisher itself to be utilized as a rotary barrel, on which the hose may be coiled or wound, and another object of the invention is to-enable the bottle to be broken or the chemical liberated by the very act of drawing off or extending the hose, whereby I reduce 0 the time necessary to putsuch an extinguisher in operation.

The invention consists in the combination, with a chemical fire-extinguisher consisting of a closed cylindric vessel and a hose connected therewith and communicating with the interior thereof, of asupport or bearing on which the extinguisher may rotate to enable the hose to be reeled upon it or extended for use, whereby the closed cylindric vessel consiituting the chemical fire-extinguisher is made to serve as a barrel for the hose. The extinguisher might have a pivot or journal at tached to its bottom; but to enable the invention to be utilized for extinguishers now in use, I provide a base-plate or piece whereon the extinguisher stands, and which has a downwardly-projecting pivot or journal fitting in a bearing or socket in a supportingbracket. Such a base-piece, in combination with an extinguisher, hose, and support,is in cluded in my invention.

(N0 model.)

. The invention also consists in a novel combination of parts, whereby the bottle will be broken or the chemical or substance released by the rotation of the extinguisher when the hose is drawn out or extended. I

The accompanying drawing represents a partly sectional elevation of an extinguisher supported and capable of operation in accordance with my invention.

A designates the extinguisher, which consists of a reservoir of anysuitable construc- .tion,and,B, is the hose permanently connected with the extinguisher at d and provided with the usual nozzle, B, in which is a stop-cock, b. From the top of the extinguisher there projects a stem, 0, here shown as screw-threaded;

and provided with a hand-wheel, d, by which itrmay be turned. The turning. of the stem or screw 0 effects the breaking of the bottle within the extinguisher, and it is obvious that if the turning of the stem etfects the breaking of the bottle, the holding of thestem stationary and theturning of the extinguisher would have a like result.

O designatesa support,whioh may be a wall, or a pillar, and D designates a bracket strongly secured thereto and projecting outward therefrom.

E- is a base-piece, which may be made of metal,and upon which the extinguisher stands. It may consist of arms radiating from a center and provided with upwardly-projecting ends e, which prevent the displacement of the extinguisher. It also has a downwardly-projecting journal or pivot, f,which fits and turns freely in a bearing, 9, provided'for it in the bracket D.

If the extinguisher were made with the view of supporting it according to my invention, the pivot or journal f might be rigidly attached to its bottom and the base-piece E dispensed with; but by the use of the basepiece I adapt my invention to the extinguishnot absolutely essential, but it is desirable in order to properly steady the extinguisher as it turns. On the top of the arm Fis a second arm, G, hinged atj,and carrying a pin,k, which projects through an aperture, Z, in the arm F, and engages with the hand-wheel (I, so as to preclude the turning of the wheel and the stem 0. Vhen it is not desired to prevent theturning of the stem 0, the arm G may be swung back, as shown in dotted lines. The pin it constitutes a detent to preclude the turning of the stern. hen the extinguisher is at rest, all the parts occupy the positions shown by full lines, the hose B being coiled upon the extinguisher A as upon a reel. Upon the breaking out of a fire, the operator seizes the hosenozzle and runs out with it, thus unreeling the hose and turning or rotating the extinguisher. The stem 0 being held against turning by the detent 7c, the bottle will be broken by the time the hose is unreeled, and all that is now required to put the extinguisher into operation is to open the stop-cock 1). Obviously this may all be done in less time than is required to set the extinguisher in operation by the old method; and the invention is also advantageous, because by the old method the operator might, in the excitement of the moment, forget to break the bottle, and he would have to drop the hose after extending it and go back to break the bottle. According to my invention delay entailed by forgetting to break the bottle is impossible, as the breaking is effected automatically by the .111010 act of extending the hose. Obviously the turning of the stem 0 might liberate the chemical or substance in other ways than by breaking a bottleas, for example, byinverting a receptacle or withdrawing a cork or stopper. I consider it far more preferable to break the bottle by extending the hose, as that operation will not then depend on the memory of the operator; but I desire to include in my invention the supporting of the extinguisher so that it may serve as a barrel for the hose, even if the bottle is to be broken by operating the stem 0 by hand, as is now necessary.

I am aware that a hose-reel has been mounted on a vertical axle or pivot so that it is capable of rotation to reel up the hose or extend it for use, and I make no claim to such reel. The novelty in my invention consists in so mounting a chemical fire-extinguisher that it may be utilized as a barrel on which to coil or reel the hose.

\Vhat I claim as myinvention, and desire to secure by Letters Patent, is

1. The combination, with achemical fireextinguisher consisting of a closed cylindric vessel and a hose connected therewith and eomnmnicating with the interior thereof, of a support or bearing on which the extinguisher may rotate to enable the hose to be reeled upon it or extended for use,whereby the closed cylindric vessel which constitutes the chemical fire-extinguisher may be made to serve as a barrel for the hose, substantially as herein described.

2. The combination, with a chemical fireextinguisher consisting of a closed cylindric vessel and a hose connected therewith and communicating with the interior thereof, of a base piece whereon the extinguisher may stand, and a support or bearing to which the base-piece is fitted, and whereon the extinguisher and base-piece may rotate to enable the hose to be reeled upon the extinguisher or extended for use, whereby the closed cylindrie vessel which constitutes the chemical fire-extinguisher is made to serve as a barrel for the hose, substantially as herein described.

3. The combination, with a chemical fireextinguisher and a hose connected therewith, of a bearing or support whereon the extinguisher may rotate to enable the hose to be reeled upon it or extended for use, and means for automatically liberating the chemical in the extinguisher by the rotatingof the extinguisher, substantially as and for the purpose herein described.

4. The combination, with a chemical fireextinguisherprovided with a projecting stein, whereby the chemical is liberated, and a hose connected with the extinguisher, of a bearing or support whereon the extinguisher may rotate to enable the hose to be reeled upon it or extended for use, and a detent for precluding the turning of said stem, substantially as and for the purpose herein described.

5. The combination, with a chemical fireextinguisher provided with a projecting stem, whereby the chemical is liberated, and a hose connected with said extinguisher. of a base support or hearing whereon the extinguisher may rotate, a top bearing for said stem, and a detent for holding the stem against turning and removable independently of said top bearing, substantially as and for the purpose herein described.

6. The combination, with the extinguisher A, provided with the stem 0, and -handle or wheel d, of the hose B, the base-piece E, the bearing 1 for said base-piece, the hinged arm F, comprising a bearing for said stem, and the secondary arm G, carrying the detent k, all substantially as herein described.
